Added value for automotive manufacturers
From the perspective of car passengers, noise is primarily a matter of comfort. But for the vehicle manufacturer, legislative pressure to reduce vehicle noise is increasing in a number of countries. Noise-reducing solutions are therefore in demand. Many manufacturers still rely on insulating barrier layers that keep sound away from the interior by reflecting it. In other words, it reverberates back into the environment. The lightweight acoustic absorbers from Freudenberg Performance Materials, on the other hand, absorb sound and convert sound energy into thermal energy. This noticeably reduces the noise level both inside and outside the car.
A technology that makes a difference
The high sound absorption of the acoustic pads is achieved through a specific ratio of fine and coarse staple fibers in the support layer, as well as the design and material of the flow layer. The interaction between these two layers is also precisely tailored. Unlike conventional market products, the support layer developed by Freudenberg Performance Materials is not mechanically sewn. This lowers weight while maintaining the same volume – an important consideration in extending the range of electrically-driven vehicles, since, for example, heat output in winter can be reduced.
The material of the flow layer, which can also function as an oscillating mass, offers additional advantages in terms of absorption and weight. Given the special engineering, the inner nonwoven surface area is increased, which improves absorption while keeping weight low. The flow layer can be used to bond the support layer on one or both sides as needed.
Multiple-layer options available
Our two-layer Finsol includes an additional AFR (air flow resistivity) layer for enhanced sound absorption. Our triple-layer Finsol features AFR layers on both sides, enabling car manufacturers to streamline logistical processes and achieve balanced acoustic performance. The nonwovens are available in rolls in various thicknesses, weights, and colors. All sound-absorbing materials are also available with a self-adhesive layer.
